Electrolysis ~ A process involving chemical change caused by the passage of an electric current through a liquid.
Galvanizing ~ The process of applying a coating of zinc to the finished product to provide corrosion protection. The coating can be applied by hot dipping or electrolytic deposition.
Aerator ~ A device screwed into the end of a faucet spout that mixes air into flowing water, and controls flow to reduce splashing. It sometimes contains a baffle to reduce flow to 2.5 gpm. On kitchen faucets, it enables a faucet to provide different flows of water, from stream to spray.
Paul McElrath - Fitting: Viscosity ~ The resistance of fluids to flow, due to internal forces and friction between molecules, which increases as its temperature decreases.
